go to auto zone. ask for 2210. its mad by Magnefine, very well made. it is for 3/8 tubing, i think that is right for 2 gen dakotas. if you need for 5/16 tubing try a wix 58964. just be sure you face it the right way , in the return line. ie fluid goes through cooler first. update: bought a auto zone 2210, is for 3/8 tubing, which i think is for a 2 gen dakota. not installed yet. my shop told me that when they install a complete Jasper trans, Jasper says to remove the check valve, that dodge put in, i think its on the right side, near the cooler.
